ZM modular-PN_TB0026_en 11 Technical Description ZM modular Profinet PN System Overview 2 System Overview 2.1 The PCM Command System The PCM Command System allows a large number of commands to trolleys to be transmitted over a control rail. Command coding is used and commands are transmitted synchronized with the mains as a combination of mains power half-waves. With the ZM modular system connected to the superordinate system controller, up to 190 different half-wave patterns can be sent as commands to trolley controllers over a control rail. Messages from the trolleys are transmitted over the signal rail to the PCM system as half-waves and full-waves. Digital modules (DI and DO) are available to record signals from external sensors (such as proximity switches) and to output signals (such as to signal lamps). 2.2 Components The ZM modular system consists of stackable modules that can be interconnected depending on the application. Base configuration: 1 x ZM central module, 1 x PCM module, 1 x EM module. Maximal configuration: 1 x ZM central module 3 x PCM module, 3 x EM module, 3 x DI module, 2 x DO module. If more modules are required, further ZM modular configurations can be added and synchronized with each other. Also see! Detailed information on the components can be found in the chapter of the respective module in these instructions. 12 ZM modular-PN_TB0026_en Technical Description ZM modular Profinet PN System Overview 2.3 Principle of the Modular PCM-System Internal module connection I/O’s and shifts Field bus Cental module ZM PCM module PCM-8-Bus Input module EM-8-Bus Input module DI-8-Bus Output module DO-8-Bus 1 module max. 3 modules max. 3 modules max. 3 modules max. 2 modules L3 N 230 VAC L+ L24 VDC L3 N 8 Outputs PCM N 8 Inputs 230 VAC 50Hz Control bar S1 Message bar M L- 8 Inputs digital 24 VDC e.g. initiators, sensors ZM modular-PN_TB0026_en L+ L- 8 Outputs digital 24 VDC e.g. signal lamp 13 Technical Description ZM modular Profinet PN Installation Notes 3 Installation Notes 3.1 Important Note - Power Supply Important note! All mentioned devices with L3-reference are designed for use with 230VAC! In case of main power of more than 230VAC it is mandatory to use a transformer to generate 230VAC (L3)! The following schematic circuit diagram shows one possible implementation, but is not included in LJU’s scope of delivery. Principle: to the ZM modules modular 14 ZM modular-PN_TB0026_en Technical Description ZM modular Profinet PN Installation Notes 3.2 Important Notes on Cable Layout Important notes on cable layout! Must be followed! The following cable layout notes must be followed to ensure interruption-free signal transmission and minimize external influences on signal transmission: Cables to PCM, EM, DI and DO modules must be laid separately from supply lines to the conductor rails and other power cables. Cables to PCM, EM, DI and DO modules must in principle be laid separately. In no case should signals from PCM and EM modules be contained in one cable. For cabling to EM, DI and DO modules, shielded cables should be used. It is recommended that shielded cables be used for cables to PCM modules. 3.3 Important Notice for Command Rail Segmentation Important notice! Definitely to be observed! Consecutive command rail segments where switchover from PCM commands ≤10 to PCM commands >10 shall be performed, must be separated by active changeover segments. Carrier entry into changeover segment with previous segment command, switchover to following segment command only when carrier brush gear is located completely within changeover segment. Combinations of PCM commands ≤PCM10 will result in recognition of the smaller command by the control box. ZM modular-PN_TB0026_en 15 Technical Description ZM modular Profinet PN Installation Notes 3.4 Installing Modules All system modules are meant to be installed horizontally in fixed housing and assembled on a NS 32 or NS 35/7.5 top hat rail. Caution! PCM modules in the ZM modular system are designed for operation at ambient temperatures of up to 50°C. The place where modules are installed should be such that cooling can take place vertically. Heat trapped in switch cabinets must be led away. 3.4.1 Module Sequencing The central module is the first (left) in the module chain. Other modules are connected to this module. The sequence of the other modules in the module chain can be chosen as desired at first installation. Optional resistance modules (RM modules) are not included in the module chain. These can be separately installed. Note! A replacement module in a pre-configured system must be installed in the same place in the module chain as the module it is replacing. 3.4.2 Mounting Dimensions The adjoining diagram shows the general dimensions of the modules. You can find module-specific widths in the Technical Data Sheet of the respective module. Width 16 ZM modular-PN_TB0026_en Technical Description ZM modular Profinet PN Installation Notes 3.4.3 Installation on Top Hat Rail The modules are attached by snapping onto a top hat rail NS 32 or NS 35/7.5 and pushing together. There are two green top hat rail clamps on the back side of the modules. To ensure stable installation, the top hat rail clamps must be positioned on the outside of a module before the module can be installed. Next, the module must be snapped onto the top hat rail. Ensure that the clamps snap in place firmly. Push adjacent modules together to integrate the module into the module chain. Ensure that plug connections to adjacent modules are correctly made. If all modules are installed, external modules in the module chain must be secured against unintentional displacement using top hat rail end clamps. 3.4.4 Uninstalling a Module Release the top hat rail end clamps of a module chain. Move modules in module chain away from each other till the module to be uninstalled is free and no longer connected to adjacent modules. Uninstall the module. Release the top hat rail clamps on the bottom surface of the module from the top hat rail with a flat-tip screwdriver by leveraging lightly (pull downwards). ZM modular-PN_TB0026_en 17 Technical Description ZM modular Profinet PN Central Module ZM-PN 4 Central Module ZM-PN 4.1 General Facts The ZM-PN module is a central module that can be controlled via Profinet and serves to generate mains-synchronized clock signals. An electronic evaluates the mains power and sends mains-synchronized +24 VDC square wave voltages with various clock combinations over the internal module connection to one or more pulse code modules. Up to 190 different codes can be generated: PCM 6 16 PCM codes PCM 10 190 PCM codes The codes are generated through relevant parameters of the PLC, which are transmitted over Profinet to the ZM-PN. These codes are transmitted over the internal module connection to the pulse code module PCM-8-Bus. The pulse code module can convert these signals directly into 230 V quasi sine half-wave combinations, since these signals run synchronized to the mains voltage, and feed them to the trolley controllers over the control rails (S1). Every pulse code command is detected depending to the software by the trolley controllers and executed. The user can freely assign the various commands like various speeds, forward/backward, for example, in trolleys controlled by frequency inverters. The hoisting function in integrated hoisting gears can be controlled in the same way. The advantages of this form of differentiated instructions, sent over only one control rail, (S1) are high jamming resistance and prevention of incorrect instructions caused by short circuit, wire break or reflections. Mix-up with the sinus signal of the mains power is avoided. 18 ZM modular-PN_TB0026_en Technical Description ZM modular Profinet PN Central Module ZM-PN 4.2 Design of the ZM-PN The mains supply of 24 VDC and 230 VAC is provided through 2 separate printed-circuit subunit terminals with threaded ends. The central module ZM is connected with the internal module connection using a 37-pin plug connector. Over the internal module connection, signals are exchangend and other modules in the module chain are supplied with 5VDC. The module is connected to the Profinet over Profinet card (integrated in the ZM). The reference phase of the trolley controllers and the modules is fixed at L3. The 24VDC power supply is safeguarded using multi fuses. The ZM-PN can be optionally fitted with a 16 x 4 LCD display module. 4.3 Monitoring and Protection Function Monitoring of the mains voltage and supply voltage Error messages via Profinet Synchronization with other central modules in the installation Display “Ready for operation“ through one green LED 3 green staus LEDs (see “Connections and Indicators of the ZM-PN) 4.4 Synchronization and Commissioning 4.4.1 Synchronization For synchronization with other central modules, these are connected with each other. The sync connections of the ZM modules must be connected in parallel. ZM 1 Sync1 Sync2 ZM 2 Sync1 Sync2 ZM x Sync1 Sync2 Wiring: It is recommended that shielded cables be used for the synchronization cables between ZM modules. Synchronization cables must be laid separately from the supply line to the conductor rails and other power cables.

Such as slow/fast forward, slow/fast reverse, variable speeds in assembly areas, hoist/lower to various positions with various speeds and various positioning behaviors. The commands transmitted over the used field bus from the PLCs at higher levels are converted by the central module into mains-synchronized timing signals and then converted by the connected pulse code module into a pulse-code, which can be clearly recognized by the trolley controller. By using mains-synchronized pulses, the output signal is always started in the voltage zero-crossing of phase L3 (disconnect in power zero-crossing). The maximum delay time between input and output signals caused by this is 10 ms at 50 Hz. The reference phase of the trolley controller and the module is assigned to L 3. The advantages: Safeguard against incorrect instructions that could be caused by short circuit, grounding or line break Differentiated control transmission over one control rail System realization without N-type rail Control from the PLC directly via the used field bus. Galvanic isolation through Optocoupler Unlimited hysteresis by using semiconductor switches Protection wiring of the output ports and short-circuit protection Error reporting over the used fieldbus. The pulse code module has 8 output ports, which means that up to 8 control rail sections can be driven by one pulse code module. 5.2 Design of the PCM-8-Bus The pulse code module PCM-8-Bus is connected to the internal module connection over a 37-pin plug-connector. The timing signals are transmitted from the central module over this internal module connection. The 8 output ports must be connected with the assigned control rail sections using printed-circuit subunit terminals with threaded terminal ends. The connection to the other modules of the module chain is realized via a second 37-pin connector. 26 ZM modular-PN_TB0026_en Technical Description ZM modular Profinet PN Pulse Code Module PCM-8-Bus 5.3 Monitoring and Protection Functions Output-side short circuit protection (semiconductor switches) LED indicator for each output (see "Connections and Indicators PCM 8-Bus") Error monitoring for: Interruption of the supply voltage Activation of the safety circuit (multi-fuse) Disturbance reports over the internal modul connection Can be used as individual disturbance report or together with several modules as composite disturbance Protective wiring of the output ports to prevent overvoltage (varistors) The signal form of the pulse code module's output signals (e.g. drive commands) is monitored by the micro-controller integrated in the trolley controller. If the signal form varies due to disruptive influences, the trolley is stopped immediately. This also holds good for line breaks, short circuits and grounding. Mixing different pulse code signals, e.g. when traversing rail sections, is possible only to a limited extent when using asynchronous drive commands (codes 2-9) (discussion and approval required). Mixing asynchronous drive commands (codes 2-9) with code numbers > 9 is to be avoided at all costs.

If the module is in the “ONLINE” state and if the counter status does not change within 2000ms, the module switches to the “OFFLINE” state, deletes all connected outputs and triggers a (local) hardware reset (if this is not deactivated by an entry of 88H in the Command Byte). The system controller must relay this counter cyclically to maintain the data exchange. Moreover, this way the system controller (independent of the bus cycle running asynchronous to the program cycle) can detect whether a new response message exists. Recommended procedure: Comparison: Counter of output data equals counter of input data? Yes => receive new data from slave! => Analyze+ trigger monitoring Program processing Set the counter of output data equal to the counter of input data + 1 10.3 Acyclic Data Exchange In the acyclic data exchange, the system controller can send data messages to the device or read from it by means of read requests or write requests. Response Code ERROR with extended error message: If the slave respond with an error, the extended error code must be analyzed (at least during the software development) if it has been generated. Following error codes are generated currently by the LJU standard firmware (ErrorCode1): 0xFF: False data length 0xB0: Access to an invalid index or Access locking error during access 0xB1: Access with an invalid length 0xB7: Access to an invalid range 0xC2: Resource is busy 0xC3: Resource not available 0xC8: Resource not reachable (no communication) 0xC9: Resource not in this segment 44 ZM modular-PN_TB0026_en Technical Description ZM modular Profinet PN Communication and System Configuration 10.3.1 Acyclic Data: System Access Indexes The following system access points are implemented in the device: 1 Access Index Meaning 01 Hex (R/W) 7F Hex (R/W) Cyclic input / output data Parameter (setting, mapping of I/O ranges) Length READ [Byte] 11 1 40 Length WRITE [Byte] 28 38 In read access, the penultimate byte contains the mains frequency with which the central module is currently working and the last byte contains the actual PCM coding.

The parameters are stored by the device in an EEPROM, so that the device can start automatically with specified parameters. A device with incorrect parameter settings cannot be correctly addressed through the cyclic service! Therefore we recommend that the ZM-PN be operated with its default configuration!

On this channel, a hard-coded drive command 0-155 is output, if Data source = 100-255: the corresponding bit in the release bit string is set to 1 for this module. No output bit for coding the drive command is needed here. The release bit string is needed only in connection with the hard-coded drive commands (data source 100-255). The various data sources can be randomly grouped to allow individual adaptation to the given requirements.
